The heads were bought new in 2017 and Ryan ported them in June of 2017, been asked a couple times and thought I would answer hear as well. If you are serious I will send you a copy of our email exchange.I have a pair for sale, they have had a stage 2 porting by Shady Dell Speed shop and they are brand new. Decided to go with a newer hemi and sell my 340, that is the reason for the sale.
Also, Ryan did a valve job and gasket matched the intake.View attachment 1631338
